“The greatest mistake you can make in life is to be continually fearing you will make one.”
What is the worst thing that can happen as an outcome of the choice you are about to make? Is your decision reversible if things go wrong? If the answer is no, take some time to think it through, understand the risks, and make a well-informed and reasoned determination.
If the decision is reversible, set a time and date to review the course you plotted against your desired outcomes and be prepared to change direction if necessary. Someone once told me, “always have an exit strategy. You never get on a submarine without knowing where the exit hatches are.”
If you plan to review and make any necessary changes, you permit yourself to make the mistakes that will inevitably happen.
